We've now had 6 led bulbs go bad in < 2 months. Going to pick up a multimeter to do some checks at the bulb wiring, but what exactly should I look for? We have a voltmeter plugged in near the sink which stays nicely in the green, but that's AC so maybe the inverter cleans that up. I'll look for spikes in voltage when switching on/off, though don't know what's normal there.
4.5″ Lexan Radiance LED Overhead - ITC Marine says 3.8W / 12V / .31A, but honestly don't know what sort of tolerance it has.
The inverter shows the input voltage, and that does range up above 14V at times, don't know whether that's expected.
